Description

Technical Field

[0001] This utility model relates to the field of synthetic leather technology, and more specifically to a synthetic leather with high cooling performance. Background Technology

[0002] When synthetic leather is made, a base fabric is needed as a support. The choice of base fabric will affect the softness and strength of the final product. It can be cotton, polyester or other fiber materials. Then, a resin (such as PU or PVC) layer is attached and fixed on the base fabric (the aforementioned process can be "base fabric layer, polyurethane foam layer coated on base fabric layer" as described in application number: CN201320281438.2). The surface of the resin (such as PU or PVC) layer also needs to be embossed, sanded, printed or other surface treatments.

[0003] Synthetic leather is generally used in:

[0004] Car interior: such as seats, steering wheel, etc., to improve the driving and riding experience;

[0005] Home furnishings: such as the covering materials for sofas, chairs and other furniture, providing a more comfortable user experience;

[0006] Clothing: Used to make summer clothes, such as jackets and trousers, to improve the wearer's comfort;

[0007] Sports equipment: athletic shoes, gloves, etc., to help athletes maintain optimal physical condition during activities;

[0008] Office chairs and office furniture: to provide a cooler working environment for people who sit for long periods of time;

[0009] The aforementioned synthetic leather has many applications that involve contact with the human body, especially in applications such as seats that require prolonged contact within a certain range. In these cases, the cooling sensation provided by the synthetic leather is particularly important. However, if the cooling function is provided solely by the surface contact of the resin layer, there is a drawback in providing this cooling performance. Utility Model Content

[0010] The purpose of this utility model is to provide a synthetic leather with high cooling performance in order to solve the above-mentioned technical problems.

[0011] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0012] This utility model proposes a high-coolness synthetic leather, including a base layer and a top layer that is bonded and fixed to its top;

[0013] It also includes multiple sets of fine pores evenly distributed on the surface layer, and a heat-conducting layer and a wear-resistant and waterproof layer that are sequentially attached and fixed to the top of the surface layer;

[0014] Each of the multiple sets of micropores is connected to the top and bottom ends of the surface layer, and the thermal conductive layer fills the multiple sets of micropores and contacts the substrate layer.

[0015] The substrate layer is thermally conductive.

[0016] As a preferred embodiment of this invention, the substrate layer is woven from thermally conductive fibers.

[0017] As a preferred embodiment of this invention, the thermally conductive fiber is formed by a blend of polyester fiber and graphene fiber.

[0018] In a preferred embodiment of this invention, the surface layer is a polyurethane resin layer.

[0019] As a preferred embodiment of this invention, the thermally conductive layer is a nano-alumina coating.

[0020] As a preferred embodiment of this invention, the wear-resistant and waterproof layer is a fluorocarbon resin coating.

[0021] The beneficial effects of this utility model are as follows:

[0022] Heat from the outer surface of the wear-resistant and waterproof layer is diffused through the heat-conducting layer to accelerate heat dissipation and improve the cooling sensation. The fine pores further accelerate the transfer of heat from the heat-conducting layer to the substrate layer, where it is rapidly diffused and conducted away, further enhancing the cooling sensation and improving comfort when in contact with the skin.

[0024] Figure reference numerals: Substrate layer-1, Surface layer-2, Micropores-3, Thermally conductive layer-4, Wear-resistant and waterproof layer-5. Detailed Implementation

[0025] like Figure 1 As shown, this utility model proposes: a high-coolness synthetic leather, comprising a substrate layer 1 and a top layer 2 that is adhered and fixed to its top;

[0026] It also includes multiple sets of fine holes 3 evenly distributed on the surface layer 2, and a heat-conducting layer 4 and a wear-resistant and waterproof layer 5 that are sequentially attached and fixed to the top of the surface layer 2; the wear-resistant and waterproof layer 5 provides the outermost protection, and the heat in contact with the outside of the wear-resistant and waterproof layer 5 is diffused through the heat-conducting layer 4 to accelerate heat dissipation and improve the cooling sensation.

[0027] Each of the multiple sets of fine holes 3 is connected to the top and bottom ends of the surface layer 2. The heat-conducting layer 4 fills the multiple sets of fine holes 3 and contacts the substrate layer 1. The substrate layer 1 conducts heat. This can accelerate the transfer of heat from the heat-conducting layer 4 to the substrate layer 1, and the substrate layer 1 can quickly diffuse and conduct heat to further improve the cooling sensation and enhance the comfort when in contact with the skin.

[0028] The substrate layer 1 is made of thermally conductive fiber woven together; it can be woven in a honeycomb pattern to form small holes similar to a honeycomb structure, which provides good air permeability, maintains a certain structural strength, and provides good thermal conductivity.

[0029] Thermally conductive fibers are formed by blending polyester fibers and graphene fibers (graphene fibers can also be carbon fibers or copper fibers); thermally conductive fibers formed by blending polyester fibers and graphene fibers not only have excellent thermal conductivity, but also take into account mechanical strength, breathability, comfort, lightweight and antibacterial properties.

[0030] Among them, the surface layer 2 is a polyurethane resin layer, which can be formed by coating and curing directly on the surface of the substrate layer 1, or by pre-making a film layer and then bonding it to the substrate layer 1 by hot pressing or other methods; as mentioned above, since it is necessary to set fine holes 3 (the fine holes 3 can be formed by mechanical or laser drilling), it is more convenient to pre-make the film.

[0031] Among them, the heat-conducting layer 4 is a nano-alumina coating. This nano-alumina coating can be applied to the top of the surface layer 2 by spraying or dipping in a sol-gel manner (it needs to enter the fine pores 3 during application), and then dried and heat-treated.

[0032] Among them, the wear-resistant and waterproof layer 5 is a fluorocarbon resin coating or a silicone rubber coating, which protects the thermally conductive layer 4 and has good weather resistance and thermal conductivity, and provides a good feel and appearance.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
